Get used to pouring the urea in the tank

Two studser by the fuel filler cap is standard equipment on many new diesel vehicles. The stricter environmental requirements mean that dieselmotorernes rensesystemer must have the use of the additive AdBlue to purify the exhaust most efficiently for the dangerous NO nitrogen oxides.

Now, there is therefore a tube for both diesel and AdBlue behind many tank closures should only, and many car owners have to regularly fill the additive in the car.

It is immediately individual, and yet not, for there are several things that you should be aware of. There are not only significant price differences, the liquid must also be handled correctly, and so it can be an expensive pleasure, if you take the error of studserne and comes to pour AdBlue in dieseltanken.

How much additive you consume depends on the brand and the way you drive. At Volkswagen, the consumption of 0.8 to 1.0 liters of AdBlue per. 1000 kilometers, and here warns the car, its driver, 3000 miles before the additive is used up.

- As a rule of thumb is the consumption of AdBlue is around one percent of fuel consumption, but it depends on the driving style, says Kenneth Pedersen, who is the technical manager at the Danish VW-importer.

that there may be differences in the specifications of the additive, even if it lives up to the overall standards. Therefore, it must have a so-called AdBlue ISO 222241-1 certification. As a rule, the additive contain is 32.5 percent urea, also known as urea while the rest is deionized water. The freezing point is about a dozen degrees below zero.

- just Like when you buy fuel at cheap or expensive companies, there may be a difference in this, even if it lives up to the overall requirements, says Kenneth Pedersen.

According to the technical chief will not hurt the engine, if the quality is poor. But it may mean that the treatment train may not work as effectively, and that the car therefore need to use more additive to achieve the same effect.

believe Lone Otto, who is head of bilistorganisationens technical advice, however, does not immediately, that there is a difference between AdBlue products.

- We do not have something that shows that there should be a difference. So you can just tanks, where it is easiest for a, for example, at the gas station, when you still the thoughts of fuel, she says.

If the vehicle runs out of AdBlue fluid, it can not run any longer and must often be reset at the workshop in order to be able to run on. Therefore recommend the Lone Otto to have a liter with in the car trunk, so you can always move on.

note, if you have a bottle with the AdBlue in the trunk of your ski break. Since the freezing point is around minus 10 degrees, the liquid can crystallize and, in the worst case, blow up the keg. So take it with indoor.

the Lone Otto does not recommend also to use for the large cans of filling, if there is a funnel, and to be aware of waste.

- It can be difficult to hit the spigot with a big dunk. And even if it is only a weak alkaline solution, it may in time allow the rust, if the paint is often exposed to AdBlue, says Lone Otto.

It is worse, if you thoughts wrong. FDM has received some inquiries from car owners, who have come to pour the additive in dieseltanken or washer fluid in the AdBlue tank.

- Like if you are going to pour petrol in a diesel tank, or diesel in a petrol tank, it is important not to turn the key, says Lone Otto.

Otherwise, the entire system namely, to be cleaned, and it is an expensive place. By avoiding to start the engine the damage can be limited.

How it works

AdBlue consists of 32% urea and deionized water. Photo: Jens Overgaard
down the urea in the AdBlue-the additive helps the diesel engine to eliminate the dangerous NO nitrogen oxides from the exhaust. It is necessary for vehicle manufacturers to meet the increasingly stringent environmental requirements.

the Additive is injected into a so-called SCR-catalytic converter, where it converts nitrogen oxides into water vapour and harmless nitrogen, while the harmful particles are removed by a particle filter.

AdBlue contains 32,5 percent artificial urea/ammonia and deionized water. It is harmless, but ammonia can in larger quantities contaminate the aquatic environment. The car's metal surfaces can also be damaged.

the Car, warn the driver when the tank with the additive, is about to be empty. If this happens, the engine can not start, and so must typically be reset at a garage. You get to pour the additive in dieseltanken or, for example, the washer fluid in the AdBlue-tank, then one should avoid turning the ignition key.

the Consumption varies from brand to brand. Some brands use one litre per day. 1000 kilometres.

Here is the cheapest on the market

There is a big difference in literprisen of AdBlue, which can fluctuate by over $ 10 per. liter. Photo: Jens Overgaard
It is immediately cheaper to tanks AdBlue direct from a stand at the gas station. It is typically possible to refuel AdBlue for six to seven dollars per. liter.

Cans are found in many places, among others in the diy and tilbehørskæder. The most expensive option is cans of one liter. Here we found the rates, which was similar to a literpris from 20 to 44 crowns. A review of the prices of 10 chains gave the following result:

Cans of five litres ranged between 70 and 90 dollars, which is equivalent to a literpris of 14 to $ 18.Cans of 10 litres cost between 70 and 150 dollars. It is a literpris of seven to 15 dollars.Jerry cans 20 litres, litres were in the 180 to 200 crowns, which is equivalent to between nine and 10 dollars per. liter.

therefore, This is not always the cheapest to buy in. But if, for example, uses 25 litres per year, a saving of 10 dollars per. liters to much money.
